Description
The THAT 1200 series of
InGenius
balanced
line receivers are designed to overcome a serious
limitation of conventional balanced input stages
— notoriously poor common mode rejection in
real world applications. While conventional input
stages may exhibit good rejection characteristics
in the lab and on paper, they perform poorly
when fed from even slightly unbalanced source
impedances — a common situation in almost any
pro sound environment.
Developed by Bill Whitlock of Jensen Trans-
formers, the patented
InGenius
input stage uses a
unique bootstrap circuit to raise its common-
mode input impedance into the megohm range,
but without the noise penalty that comes from
high-valued resistors. InGenius line receivers
maintain their high CMRR over a wide range of
source impedance imbalances — even when fed
from single-ended sources.

under real-world conditions
Excellent solution for hum and
groundloop suppression
Transformer-like noise rejection in
an 8-pin IC, at fraction of
transformer cost and size
